Re: Vacuum pump for sampling
Nick I have a oil type
pump on my vacuum oven and it uses scrubbers on the exhaust as there is quite a
haze without it. Do you get an oil haze out of the exhaust port? ?All that is going
back in so use an exhaust filter. ?An inlet filter will prevent oil back-streaming
from the pump to the evacuated chamber which is why these are used on alpha spec
systems. I would be wary of using ?that pump for that purpose. Get a diaphragm type
pump there are plenty on Ebay around $100. I also realize that we¡¯re not
dealing with a closed vacuum system but why take chances. At the very least
disconnect the vac line when finished as diffusion rules.

I have an old SKC air sampler pump. It sucks, but I can also get it to pump. It

Re: Vacuum pump for sampling
Well I shoved the cord wires in an extension cord and it actually seems to run okay on 120vac.? Sounds pretty good,? not too loud.? ?If I completely plug the inlet hoses it slows down enough to kick in the starter again though.?
This model should be rated at 1.1-1.3cfm.
I think I'll install a proper 120 plug on the cord and hook it up to the SmartCAM and see what airflow it reports.?

Nick that looks like a

Don¡¯t push air into the CAM
valve outlet. You want to use a vacuum for airflow to the detector. You need to
pull room air into it not push air in backwards. Only hook up a vacuum line to
the valve outlet on the CAM head ( note the airflow direction on that valve
fitting) and adjust the flow with the valve on the CAM head. Pushing air in may
blow filter crap onto the detector face ruining it.
Start with using indoor
room air it should have enough radon to see without using an unknown source. You
should see some 0.x to 2 pCi/l or so.

Need some advice.
What sort of airflow does the Eberline 6A expect ?
Or more useful is what sort of airflow should I use ? I don't know how make use
of the airflow control circuit in the 6A so I thought I might plumb the air
directly from a pump.
I have an old SKC air sampler pump. It sucks, but I can also get it to pump. It
goes up to 5l/min
4l/m @ 20" of back pressure.

Re: Alpha and Beta particle Spec
Nick
Don¡¯t push air into the CAM
valve outlet. You want to use a vacuum for airflow to the detector. You need to
pull room air into it not push air in backwards. Only hook up a vacuum line to
the valve outlet on the CAM head ( note the airflow direction on that valve
fitting) and adjust the flow with the valve on the CAM head. Pushing air in may
blow filter crap onto the detector face ruining it.
Start with using indoor
room air it should have enough radon to see without using an unknown source. You
should see some 0.x to 2 pCi/l or so.
